Patented Apr. 7, 1931 UNITED STATES- ANTON C. MENGE, OF NEW ORLEANS, LOUISIANA FILTER Application filed November 13, 1929. Serial No. 406,924.

The object of this invention isto rovide a simple, inexpensive and efficient mec anism whereby water may be filtered automatically as it is drawn from a supply for use. The invention provides a series of cells containing filtering material through which the water successively rises, overflowing from the top cell of the series and. collecting in an outer casin from which it is drawn for use. '10 The invention is illustrated in the accom anying drawing and consists in certain novel ibatures which will be hereinafter first fully described and then particularly defined 1n the ap ended claim. In t e drawing:

Figure l is a vertical section of a filter embodying the present invention, and

Fig. 2 is a detail plan View of one of the partitions which separate ad oining cells.

In carrying out the invention, there IS provided an outer casin 1 which may be of any suitable or preferre dimensions and 1s provided with a removable cap plate or upper head 2 from which there rises centrally a vent tube 3. Upon one side of the casin is a gage tube 4 through which the height 0 the water in the casing may be easily noted, th s tube Ming of glass and being in communication with the casing at the top and bottom of the same, as shown and as will be understood. In the bottom of the casing is a drain plug .5 to facilitate cleanin when necessary and also at the bottom is a raw-off faucet 6 which ma be of an a roved type.

l isposed viith iii the casing and in spaced relation thereto is an inner shell 7 preferably of cylindrical formation and of some durable material which will withstand dam ness. ,This inner shell is supported with1n the casing by brackets or feet 8 which are secured to the lower end of the shell and to the bottom of the outer casing so. as to support the shell above the bottom. Within the shell a plurality of brackets or lugs 9 are provided thereon, said brackets being arranged in series extending the entire height of the shell, as shown, and being intended to support perforated partitions or disks 10 which are provided in their peripheries with notches 11 whereby each disk may be slipped filtering material may be employe past upper brackets to reach the brackets upon which it is to rest and then by being turned so as to bring the notches out of alinement with the brackets to rest upon the brackets in an obvious manner. These disks are provided with openings 12 therethrough so that the water may pass through the disks from one cell to a succeeding cell. Upon reference to Fig. 1, it will be noted that the disks are supported by the brackets in spaced relation and they, therefore, define a plurality- 'of cells within the shell which are adapted to contain filterin material. The lowermost cell or the space below the lowest disk 10 is left empty so that the water may accumulate therein, as will be understood, the force of the water being thereby reduced so that it will not flow through the openings 12 in the lowest disk with sufiicient velocity to disturb the filtering material which is disposed above said disk. While an 1 suitable d I prefer to use and have indicated lumps of charcoal 13 in the first and third cells counting upwardly while the second and fourth cells contain sponges 14. At the top of the shell, there is provided an additional disk 15 which is the same in all respects as the disks 10, except that the notches 11 may be omitted, said disk 15 resting directly on the sponges on the top cell and being adapted to compress said sponges so that the flow of water through the same will be eflectually retarded and any foreign matter in the water will be removed therefrom in an eflicient manner. A domeshaped perforated cap 16 is secured upon the upper end of the shell 7 and mounted centrally in said cap is a pressure screw 17 which bears upon the disk 15 so that if the pressure screw be turned home said disk 15 will be caused to compress the uppermost sponges 14 in the manner previously mentioned. In the upper end portion of the outer casing between the cap plate 16 and the head .2 of the casing is arranged a float 18 from which a needle valve stem 19 rises to play within the vent tube 3. As the level of water within the casing 1 rises, the float will be raised and the valve stem 19 will engage the exit opening 20 in the vent tube so as to cut the bottom of the reservoir and has its lower end upturned to ass through the bottom of the casing 1 and be secured in the bottom of the inner shell 7 to establish communication with the interior of the shell. Cut-ofl' valves -23 of any approved form are provided in the pipe 22 at convenient points so that the flow of the water may be easily controlled. The

water flowing from'the reservoir will pass upwardly into the shell 7 and the Weight of vthe volume of water in the pi e 22 and the pressure exertedthereon by the ody of water in the reservoir will cause an upward flow through the several cells of the filter so that the impurities will be removed and the clear Water may escape through the perforations of the 'cap 16 and overflow into the outer shell. The level of the water in the shell will be indicated in the gage tube 4 and the flow may be cut 03 or established as may be necessary to maintain the water at such level as experience may indicate to be advisable.

The water is drawn off for use through the faucet 6 and, of course, the level of the water in the outer casing will drop as water is drawn oil. The float 18 and valve 19 will rise and fall with the level of the water at the top of the casing and the exit opening 20 will, consequently, be opened or closed so that whenever the casing is about full inflow of air will be arrested and when the level drops air may be admitted so'that a vacuum willnot be established to interfere with the circulation of the water while at the same time there will be no trapping of air to-prevent free flow of the water from the filter cells.

' The device is exceedingly simple in the construction and arrangement of its parts and will operate entirely automatically. After therefrom, a liquid inlet rising through the bottom of the casing and passing into the bottom of the shell, a series of perforated disks supported within the shell, filterin media between the disks, the uppermost dis resting directly on and being supported sole- 1y by the uppermost filtering medium, a perforated cap at the upper end of the shell through which liquid may overflow into the casing, a pressure screw mounted in said cap and bearing on the uppermost disk a vent tube rising from the top of the casing, a float in the casing in ali ment with said screw, a valve stem rising rom said float. and playing in said vent tube and adapted to o n and close the exit thereof, the float being 'sposed over thepressure screw whereby it may rest thereon to limit the opening movement of the valve, and a draw-ofl' device at the lower end of tne casing.

In testimony whereof I aflix my si ature.
